The last 3 weapons for now are added in, the only way you can use them is to throw them at a distance from the enemy. They all are very limited and very powerful weapons that you can use to get yourself out of a bad situation or finish off a group of enemies. The molotov cocktails are deadly since you and your allies can catch fire if you throw it too close, so give it some distance before you lob fiery death upon your enemies.
